Changing the seed switch
When you change the seed switch for a fabric, the Management application performs the following
checks in the order they are listed:
• Identifies all switches and removes those running unsupported firmware version.
• Identifies which of the remaining switches are running the latest firmware versions.
• Filters out those switches that are not reachable.
• Identifies which switches are Virtual Fabric-enabled switches (Fabric OS only).
If there are Virtual Fabric-enabled switches, the Management application only uses these
switches as recommended seed switches. If there are no Virtual Fabric-enabled switches,
continue with the next check.
• Identifies which switches are Virtual Fabric-capable devices (Fabric OS only).
If there are Virtual Fabric-capable switches, the Management application only uses these
switches as recommended seed switches. If there are no Virtual Fabric-capable switches, the
Management application uses the list from the second check.
To change the seed switch, complete the following steps.
1. Select Discovery > Fabrics.
The Discover Fabrics dialog box displays.
2. Select the fabric for which you want to change the seed switch from the Discovered Fabrics
table.
If a device joins or merges with a fabric and fabric tracking is active, you must accept changes
to the fabric before the new devices display in the Seed Switch dialog box. For more
information about fabric tracking, refer to “Fabric tracking” on page 130.
3. Click Seed Switch.
If the fabric contains other switches that are running the latest version and are also
HTTP-reachable from the Management application, the Seed Switch dialog box appears.
Otherwise, a message displays that you cannot change the seed switch.
4. Select a switch to be the new seed switch from the Seed Switch dialog box.
You can select only one switch. Only switches that are running the latest Fabric OS version in
the fabric are displayed. The current seed switch is not displayed in this list.
5. Click OK on the Seed Switch dialog box.
If you are not already logged in to the seed switch, the Fabric Login dialog box displays.
If you are successfully authenticated, the fabric is deleted from the Management application
without purging historical data, and the same fabric is rediscovered with the new seed switch.
6. Click Close on the Discover Fabrics dialog box.
